10.2.2 DC Input Operation
Each General I/O Port provides sixteen 24 Vdc inputs. Each Port
contains two groups of eight inputs: group A = input 1 through
output 8, group B = input 9 through output 16. Each group can be
configured as sourcing or sinking. Connect the DCSS pin (DCSS1
for Group A, DCSS2 for Group B) to IO24C for a sourcing
configuration. Connect the DCSS pin (DCSS1 for Group A,
DCSS2 for Group B) to +24 Vdc for a sinking configuration. An
example of connecting input devices in both a sink and source
configuration is shown in
Figure 10-4 .
In addition, the first input of each Group (Input 1 of Group A, and
input 9 of Group B), can be programmed to provide a processor
interrupt on either a low-to-high or high-to-low transition.
For more information on DC input operation, refer to Section A.2
on page 171 of Appendix A .
